Adjusting the stock sight?

[reflex]

Shot my P-07 today for the first time (I like!) and it's shooting to the left.  The front sight allows for no adjustment, save filing it down if the gun shot too low.  Anyone know how to adjust the rear sight?  It does not have an allen and appears to be staked in some way.  Anyone done this yet?

I'll probably end up upgrading from the stock sights eventually, but for now I need this gun to shoot to point of aim.

thanks!

    You may be jerking the trigger resulting in the pistol shooting to the left.  Have an experienced gunhand use it first to determine whether it is you or the pistol!

Thanks...but I am one.  Been shooting for 25+ years.  This is just my first CZ.  With most of my 1911's 1.5" at 15 yds dead center is np.  It's the pistol.
